<h1>Butanol, C<sub>4</sub>H<sub>10</sub>O</h1>

Butanol (C<sub>4</sub>H<sub>10</sub>O) refers to a group of four isomeric alcohol compounds with a four-carbon structure. The isomers include n-butanol (or 1-butanol), isobutanol (or 2-methyl-1-propanol), sec-butanol (or 2-butanol), and tert-butanol (or 2-methyl-2-propanol). Of these, n-butanol is the most commonly referred to when discussing "butanol."

Butanol is a colorless liquid at room temperature with a characteristic alcoholic odor. It is moderately soluble in water but is very soluble in most organic solvents. It's utilized in a wide variety of applications, including as a solvent in the manufacturing of resins, plasticizers, and other chemicals. It's also employed in the formulation of paints, coatings, varnishes, and inks. In addition, butanol is considered a potential biofuel, as it can be produced from biomass sources and has properties comparable to gasoline.
